As the medical health service is closely related to health of general public,making harmonious hospital inevitably becomes an important link in constructing a harmonious society.The mutual trust is the most fundamental and active factor in physician-patient relationship.Therefore,construction of a harmonious hospital in the new situation should embark from the hospital connotation construction in great details to reconstruct a harmonious medical relation with mutual trust between doctors and patients.

Objective To investigate the expression profile of long non - coding RNAs(lncRNAs) in acute kidney injury (AKI) rats upon astragaloside IV(AS - IV) treatment. Methods Eight male SD rats were selected and randomly divided into two groups. AKI model group(group 1):4 rats were subjected to ischemia - reperfusion(I/ R);AS - Ⅳ pretreatment group (group 2):4 rats were orally administered AS - Ⅳ for 7 days prior to I/ R. Renal tissues were collected after I/ R treatment of 24h,total RNA was extracted from renal tissues and tested for quality. Sequencing experiments were carried out after being qualified. The threshold set for up - and down - regulated genes was a fold change(group1 / group2)≥2 and P≤0. 05. Afterwards,GO analysis and KEGG analysis were used to determine the roles that these differentially expressed mRNAs played in these GO terms or pathways. Results Two hundred and thirty - two lncRNAs were differentially expressed(127 lncRNAs were up - regulated and 105 lncRNAs were down -regulated). Three hundred and forty - one mRNAs were differentially expressed(178 mRNAs were up - regulated and 163 mRNAs were down - regulated). GO analysis indicated that differentially expressed mRNAs were mainly involved in biological processes such as nucleosome assembly,chromatin assembly,nucleosome organization,chromatin assembly or disassembly and DNA conformation change. GO analysis indicated that differentially expressed mRNAs were mainly involved in cellular components such as nucleosome,protein - DNA complex,nuclear chromatin,chromatin and nuclear nucleosome. GO analysis indicated that differentially expressed mRNAs were mainly involved in molecular functions such as protein heterodimerization activity,protein dimerization activity,DNA binding,nucleic acid binding. Signal pathway analysis indicated that lncRNAs and mRNAs were involved in systemic lupus erythematosus,alcoholism and viral carcinogenesis. Conclusion LncRNAs expression differed significantly in renal tissues of AKI model group and AS - Ⅳ preconditioning group. Study of the biological functions and pathways of these lncRNAs indicated that they may be involved in the mechanism of AS - Ⅳ ameliorated ischemic acute renal injury.

Objective:To analyze the safety and efficacy of PD-1 inhibitors versus chemotherapy or ipilimumab in advanced melanoma.Methods:PubMed,CNKI,VIP and Wanfang databases were searched to collect randomised controlled trials of PD-1 inhibi-tors in treatment of advanced melanoma.The search time was from the establishment of the database to May 1,2022.Two reviewers independently screened the literature,extracted data,and assessed risk of bias of included studies.Meta-analysis was performed using RevMan5.4 and STATA16 software.Results:A total of 7 studies were included.Meta-analysis results show that:①Safety:Compared with chemotherapy,PD-1 inhibitor treatment had fewer adverse events,especially in the blood system;compared with ipilimumab alone,PD-1 inhibitor combined with ipilimumab had more adverse events,especially liver function indicators;there was no signifi-cant difference in the incidence of total adverse events between PD-1 inhibitor monotherapy and ipilimumab monotherapy.②Efficacy:The PFS,OS and ORR of PD-1 inhibitor versus chemotherapy or ipilimumab were HR=0.54,95%CI(0.45,0.62),P<0.05,HR= 0.69,95%CI(0.58,0.80),P=0.03 and OR=3.16,95%CI(2.59,3.86),P<0.05,respectively.Conclusion:PD-1 inhibitors have good efficacy in treatment of advanced melanoma,while different combination methods and different control treatments may have different efficacy.Limited by the quantity and quality of included studies,more research evidence is needed to support this.

Objective:To investigate the prenatal ultrasonographic features and diagnosis of 16p12.2 copy number variation (CNV).Methods:This retrospective study recruited seven fetuses with 16p12.2 microdeletion/microduplication in the First Affiliated Hospital of Fujian Medical University from January 2017 to December 2021. Data, including the prenatal diagnostic indications, ultrasound findings, karyotypes, genetic testing and mutation tracing results, pregnancy outcomes, and postnatal follow-up data, were summarized with descriptive statistical analysis.Results:Prenatal ultrasound indicated three fetuses with structural abnormalities, including one case each of multiple malformations, interventricular septal defect, and cleft lip and palate. The other four cases were positive for ultrasonic soft markers involving the heart and kidney. The chromosome karyotypes of the seven fetuses were normal. Single nucleotide polymorphism array (SNP array) results showed that four cases had a 381.7-542.4 kb microdeletion containing three genes ( OTOA, METTL9, and IGSF6) in Online Mendelian Inheritance in Man (OMIM) at 16p12.2 (distal region) and three cases had a 484.0-701.7 kb microdeletion/microduplication containing four OMIM genes ( UQCRC2, CDR2, EEF2K, and POLR3E) at 16p12.2 (proximal region). Five (cases 1, 2, 4, 5, and 6) out of the seven fetuses inherited the variants from their phenotypically normal mother/father, and among them, three (cases 2, 4, and 5) were delivered at term and healthy. Two cases (cases 3 and 7) refused to undergo pedigree verification. Case 3, a full-term infant, underwent ventricular septal defect repair three months after birth, and no abnormality was found at 18 months of age. Conclusions:No specific phenotype presents in fetuses with 16p12.2 microdeletion/microduplication in prenatal diagnosis. OTOA gene is the key gene associated with abnormality in the distal region of 16p12.2. Pedigree analysis is conducive to preventing unnecessary termination of pregnancy.

[Abstract] Objective: To systematically evaluate the efficacy and safety of nivolumab plus ipilimumab versus nivolumab monotherapy in the treatment of malignant tumors, so as to provide evidence-based medical proof for clinical administration. Methods: Databases, such as PubMed, CNKI, VIP, and Wanfang Data, were searched from January 2000 to January 2022 to collect the clinical trial data in terms of nivolumab plus ipilimumab versus nivolumab monotherapy for malignant tumors were published in both domestic and abroad. Two reviewers independently evaluated the quality of included RCTs, and extracted and cross-checked the data. RevMan 5. 4 was used for the Meta-analysis. Results: A total of 7 RCTs studies including 10 articles were included. Compared with the nivolumab monotherapy group, the OS of patients in the combined treatment group was significantly improved (HR=0.86, 95% CI:0. 75-0.99, P=0. 03), and the PFS was significantly prolonged (HR=0.69, 95% CI: 0.55-0.85, P=0.000 6). However, as for safety, treatment-related adverse events (OR=3.18, 95% CI: 1.55-6.55, P=0.002) and adverse events leading to drug discontinuation (OR=7.11, 95% CI: 4.85-10.42, P<0.000 01) in the combination therapy group were significantly higher than those in the monotherapy group. Conclusion: Compared with nivolumab monotherapy, nivolumab plus ipilimumab can significantly improve the OS and PFS of tumor patients, but is also associated with more treatment-related adverse events and adverse events leading to drug discontinuation. Therefore, it is necessary to pay attention to follow-up and regular monitoring to prevent the occurrence of serious adverse reactions.
